That kind of looks like a rotary compressor. I’m not sure what the psi reading will be. Just charge slowly until you have a full frost pattern, and no frost on the low side line in the machine compartment. |

Thank you so much for your advice! I will check if there is a tag or info on the compressor before I refill. Thanks again, Greg |

Keep in mind that my GE is a 1960 upright model, and circa 13 cu. ft....which is somewhat larger than the wall hung units. Mine takes a max of 3 lb. worth of R12:

Your gauges can only read pressure. To charge 3# of r12, you first have to vacuum the system completely (with a 2 stage vacuum pump), then charge the system by weighing it in. |

Wow, I am not sure where to start, the posts above are either mostly or completely wrong.
It is best to use R-12 if possible in these older refs.
The only correct way to charge this ref is to measure the refrigerant in, Gauges are never used for charging a residential refrigerator.
On these GEs the correct charge weight in in the service manual, NOT on the model # tag, this ref does not require anywhere near 3 pounds of R-12, probably somewhere between 7 and 12 oz.
This is a piston compressor with a low side shell.
You should remove the leaky clamp-on charging port someone put on this ref. Then either use the GE charging tool with the built-in charging port or if the charging tool is not available braze on a proper charging port.
Then you need to pull a proper vacuum and see if it holds a vacuum, it is also ideal to replace the filter dryer.
If it holds a vacuum, then charge by weight and you should be in business.
